Data Modelling is the process of creating the data model to store data in the Database. It helps to create a visual representation of the data and improves business policies, regulation, and even government policies on the data. It represents the data objects, the relation between rules and the data objects.

There are three types of Data models that are as follows:

                                    • Logical: The logical data model is created by Data Architects and developers that defines how the system has to be implemented. This data model is to develop a technical map of data structures and rules.

                                    • Conceptual: The Conceptual data model is used to organize, define, and scope the business rules and concepts. It determines what the system includes.

                                    • Physical: Physical data models is the actual implementation of the database. It defines how the system is implemented using a DBMS system. Developers and DBA usually create this data model.

Data design tools help the users to create the database structure from diagrams, and graphics so that to create a perfect data structure as per the requirement. Following are the list of Data modelling tools which include both commercial and open-source software. Let’s check out the list in brief.

            • Benefits of using Data Modelling tool

The following are the benefits of using Data Modelling tools:

High application quality: The data modelling process is the most productive way to gather the data and complete business data requirements and business rules to ensure the system operates in an intended manner. Before creating the database, the architect’s blueprint is generated and thus improves the quality of the application.

Enhanced integration: The creation of a meta-repository gives a common vocabulary, resolves discrepancies, and identifies the redundancies and relationships with the use of data modelling tools.

Better performance: Data modelling provides a well-structured database typically that runs faster than expected. It provides DBAs to understand the database and modify it for better performance. The concepts in the data model must be crisp and coherent to achieve optimal performance. 

Reduces errors: Data modelling tools help to reduce data errors and application errors. The tools are used to provide well-defined concepts that help the developers to resolve the errors easily. 

Business Intelligence: A good data model built-in queries and reports elements required is a start point for data mining. It identifies the patterns and trends to make predictions that help a business to tackle the challenges and opportunities. 

Improved Collaboration: Data model helps to communicate with the users within and across the organization. It helps to share the documents with each other using other databases. 


On wrapping up, Data Modelling tools help to create database structure from diagrams, and it makes it easy to create a perfect data structure as per the business requirement. In this article, we have discussed different types of Data Modelling tools and the benefits of using Data Modelling tools. Hope you had relevant information.
